Abstract: The present invention provides, among other things, an improved method of treating cystic fibrosis (CF) in a human subject. The method comprises administration of a composition comprising an mRNA encoding a Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein by nebulization at a dose between 7 mg and 25 mg. A suitable dose for use in the method of the invention is selected on the basis that it provides the human subject with at least a 3% increase in absolute change in ppFEV1 (percent predicted forced expiratory volume in one second) from baseline ppFEV1 at two days following the administration. In addition or alternatively, the dose is selected to provide the human subject with at least a 2% increase in absolute change in ppFEV1 from baseline ppFEV1 at one week following the administration.

Abstract: The present invention, provides a method of treating cognitive impairment of Hunter syndrome. Among other things, the present invention provides a method comprising a step of administering intrathecally to a subject in need of treatment a recombinant iduronate-2-sulfatase (I2S) enzyme at a therapeutically effective dose and an administration interval for a treatment period sufficient to improve, stabilize or reduce declining of one or more cognitive, adaptive, motor, and/or executive functions relative to a control.

Abstract: The present invention, provides a method of treating cognitive impairment of Hunter syndrome.

Abstract: Detecting glycosaminoglycans (GAGs) and/or determining the level of one or more glycosaminoglycans can be useful, e.g., in identifying or monitoring various medical conditions, the status of patients having various medical conditions, and/or the response to treatment of individuals having various medical conditions. The present invention provides methods for detecting glycosaminoglycans and/or determining the level of glycosaminoglycans through the use of, e.g., mass spectrometry.

Abstract: The present invention provides, among other things, effective treatment for Sanfilippo Syndrome Type A (MPS IDA) based on intrathecal delivery of recombinant heparin N-Sulfatase (HNS) enzyme. In some embodiments, the present invention includes methods of treating Sanfilippo Syndrome Type A (MPS MA) Syndrome by intrathecal administration of a recombinant HNS enzyme at a therapeutically effective dose and an administration interval for a period sufficient to decrease glycosaminoglycan (GAG) heparan sulfate level in the cerebrospinal fluid (CSF) and/or urine relative to a control.

Abstract: The present invention provides, among other things, effective treatment for Sanfilippo Syndrome Type A (MPS IIIA) based on intrathecal delivery of recombinant heparin N-Sulfatase (HNS) enzyme. In some embodiments, the present invention includes methods of treating Sanfilippo Syndrome Type A (MPS IIIA) Syndrome by intrathecal administration of a recombinant HNS enzyme at a therapeutically effective dose and an administration interval for a period sufficient to decrease glycosaminoglycan (GAG) heparan sulfate level in the cerebrospinal fluid (CSF) and/or urine relative to a control.

Abstract: The invention provides methods of assaying fatty acid amide hydrolase (FAAH) activity adaptable for high through-put screening. The methods provide for separating a labeled substrate from at least one labeled hydrolysis product, the separation facilitating the quantification. The invention also provides methods of identifying a compound to be tested as an inhibitor or an activator of FAAH activity through the addition of the compound to be tested to a reaction mixture and comparison of the enzyme activity in the presence and absence of the compounds to be tested. The methods are adaptable for use in detecting altered FAAH activity in patients, for example, those at risk for in vitro fertilization failure, or at risk for, or suffering, addictions.

Abstract: Certain hexahydro-pyrrolo-isoquinoline compounds are histamine H3 receptor and serotonin transporter modulators useful in the treatment of histamine H3 receptor- and serotonin-mediated diseases.
